Premium Python Backend Development VendorBackend Development
Senior Python engineers who ship. Fixed price, 8-12 weeks, no surprises.
IRPR is a premium python backend development vendor. We build production-grade backends using FastAPI, Django, Celery, and PostgreSQL. Our engineers write clean, typed Python with full test coverage and CI/CD pipelines.
Every engagement starts with a 2-week Roadmap phase. We deliver a fixed price quote before any coding begins. Typical MVPs run 8-12 weeks and cost $80K-$250K. We handle HIPAA, PCI-DSS, and SOC 2 compliance for healthcare, fintech, and SaaS clients.
CTOs hire us when their in-house team lacks Python depth. Startup founders hire us to ship a production-ready API in under 12 weeks. Enterprise architects hire us to replace legacy Java or PHP backends with modern Python microservices.
Types of software we ship.
REST API development
FastAPI or Django REST Framework APIs with OpenAPI docs, JWT auth, rate limiting, and PostgreSQL. Deployed in 8-10 weeks.
GraphQL API development
Strawberry or Ariadne GraphQL APIs with resolvers, subscriptions, and DataLoader batching. Built for real-time web and mobile apps.

Why choose a premium python backend development vendor
Average python shops deliver late, over budget, with untested code. IRPR delivers on time, on budget, with 90%+ test coverage.
We are a premium python backend development vendor because we only hire senior engineers. Every IRPR engineer has 8+ years of Python experience. We do not outsource to junior developers or offshore teams. You get a senior engineer who owns your backend from day one.
Our process eliminates surprises. In the 2-week Roadmap phase we define every endpoint, every database table, and every integration. You get a fixed price and a fixed timeline. No scope creep. No hourly billing. No excuses.
How IRPR compares to other python backend vendors
Most agencies promise senior talent but deliver juniors. IRPR is different.
Generic python agencies often staff projects with one senior architect and three junior developers. The junior team writes the code, the senior reviews it, and the client pays for rework. IRPR does not work that way. Every engineer on your project is a senior with 8+ years of Python experience.
We also fix the pricing problem. Most vendors charge hourly and profit from slow development. IRPR charges a fixed price after the Roadmap phase. We are incentivized to build fast and well, not to drag out the project.
- junior engineers write your code
- hourly billing with no cap
- no compliance experience
- untested code shipped to production
- no ownership after delivery
- scope creep is your problem
- senior Python engineers only
- fixed price after 2-week Roadmap
- HIPAA, PCI-DSS, SOC 2 ready
- 90%+ test coverage on every project
- full source code ownership
- scope changes are priced, not hidden
Our process for premium python backend development
We follow four phases that turn your idea into a production backend.
The Idea phase takes 1 week. We review your product requirements, user stories, and technical constraints. We identify the right Python stack for your use case: FastAPI for high-performance APIs, Django for admin-heavy apps, or a custom microservices architecture.
The Roadmap phase takes 2 weeks. We define every API endpoint, database schema, integration, and deployment step. You get a detailed project plan with a fixed price and a fixed timeline. No coding starts until you approve the Roadmap.
What ships when you hire IRPR as your python backend vendor
You get a production-ready backend with everything needed to scale.
Every engagement includes a fully deployed backend with CI/CD, monitoring, and documentation. We do not hand over code and walk away. We set up your infrastructure on AWS, GCP, or Azure and train your team on how to maintain the system.
You also get a 30-day post-launch support period. We fix any bugs, answer any questions, and help your team take over. After that, we offer ongoing maintenance at a fixed monthly rate.
- Source code in your GitHub or GitLab repo
- CI/CD pipeline with GitHub Actions or GitLab CI
- Dockerized application with docker-compose
- PostgreSQL database with migrations
- API documentation via Swagger or ReDoc
- Sentry error tracking and Datadog monitoring
- Load testing report with k6 or Locust
- Deployment playbook for AWS, GCP, or Azure
- 30-day post-launch support with SLA
- Full test suite with 90%+ coverage
What we ship in this practice.
Multi-tenant SaaS API

Content recommendation engine
Created a Python backend with a collaborative filtering engine for a media platform. Increased user engagement by 35% and reduced content load times by 50%. Tech stack: FastAPI, PostgreSQL, Redis, scikit-learn, Docker.
Why teams hire us.
Fixed price, not hourly
Every project gets a fixed quote in the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. You know the cost before we write a single line of code.
Senior engineers only
IRPR does not hire junior developers. Every engineer on your project has 8+ years of Python experience. You get a senior who can design, build, and deploy your entire backend.
Compliance ready
We have built backends for HIPAA, PCI-DSS, and SOC 2 environments. We know how to handle PHI, PII, and payment data. Your backend passes audits on the first try.
Full code ownership
You own every line of code we write. No licenses, no royalties, no vendor lock-in. We put the source code in your repo from day one.
Production monitoring included
Every backend ships with Sentry error tracking and Datadog monitoring. We do not disappear after launch. We monitor your system for 30 days post-launch.
8-12 week MVPs
We ship production-ready backends in 8-12 weeks. No 6-month delays. No endless rewrites. You get a working API in under 3 months.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
